💡 Problem Formulation: How do you transform raw data into a set of features that TensorFlow can work with? Defining feature columns in TensorFlow is crucial when you’re preparing data for a machine learning model. Let’s say you have customer data and you want to predict churn; you’ll need to transform customer attributes into feature … Read more
💡 Problem Formulation: In natural language processing, tokenization is a foundational step. Given a string of text, such as “TensorFlow is powerful and user-friendly!”, we want to split the text into tokens (words or symbols) based on whitespace to get an array of tokens: [“TensorFlow”, “is”, “powerful”, “and”, “user-friendly!”]. In Python, TensorFlow Text provides various … Read more
💡 Problem Formulation: When processing text with TensorFlow in Python, identifying whether a string has a certain property can be essential for text analysis, filtering, or preprocessing. For example, we might need to check if a string contains a valid date, is written in a certain language, or contains a specific keyword. Efficiently identifying these … Read more
💡 Problem Formulation: In scenarios where data needs to be tokenized, such as text preprocessing for natural language processing tasks, it’s often necessary to split strings at the character level. For instance, turning the string “hello” into [“h”, “e”, “l”, “l”, “o”]. TensorFlow Text provides a Unicode-aware method to accomplish this, which we’ll explore using … Read more
💡 Problem Formulation: Working with text data often involves parsing and tokenizing strings, which can be especially challenging with UTF-8 encoded strings due to the variety of character sets.
